Comparative Study
Biomechanical comparisons of plate placement for medial tibial plateau fractures (Schatzker type IV): A biomechanical study using porcine tibias.
Biomechanical studies on medial tibial plateau fractures (MTPFs) (Schatzker classification type IV) are currently few, while studies using locking plates (LPs) placed on medial proximal tibias are unavailable. Hence, we compared the biomechanical properties of plate osteosynthesis at the medial and anteromedial placements using large- and small-fragment LPs in porcine bones. ⋯ Medial LP placement for MTPFs in porcine bones resulted in significantly lower posterior step-offs after cyclic loading than anteromedial placement, and large-fragment LPs for MTPFs caused significantly lower fracture gaps in the central articular after cyclic loading than small-fragment LPs.

Fragility fractures without significant trauma of the pelvic ring in older patients have an increasing incidence due to demographic change. Influencing factors other than osteoporotic bone quality that lead to an insufficiency fracture are not yet known. However, it is suspected that the pelvic tilt (PT) has an effect on the development of such an insufficiency fracture. This study explores the influence of the PTs in patients with insufficiency fractures of the posterior pelvic ring. ⋯ The study demonstrates a significant extension of the PT angle of individuals with insufficiency fractures when compared to those with lumbago. The result suggests a potential association between pelvic tilt and fracture susceptibility.

Review Case Reports
A novel surgical technique for removal of intramedullary nails when there is a failure of the proximal extraction device: Report of two cases and review of literature.
Diaphyseal fractures of the tibia is a common injury with an incidence of 16.9/100,000 population. Surgical treatment with intramedullary interlocking nail is the treatment of choice in closed diaphyseal tibial injuries. Removal of the nail is required in non-union, infected implant, implant failure or during exchange nailing procedure. ⋯ There are only a few articles described for the removal of an intramedullary nail when there is failure of the proximal extraction device. The failure of the proximal extraction device occurs due to the use of ill-fitting extraction bolts, cross threading and the presence of a very tight nail leading to stripping of the proximal threads. We describe a simple and novel technique with the use of the Stainless-Steel wire along with the extraction bolt when there is a failure of proximal extraction device for the extraction of cannulated or solid intramedullary nails.

The Clinical Frailty Scale (CFS) is a 9-point scaling system used to categorise the frailty of patients. The CFS is well-established as a prognostic tool for decision-making within healthcare settings. However, the relationship between the CFS as a predictor for orthopaedic outcomes is limited. This review aims to provide an overview of the efficacy of the CFS as a prognostic tool for predicting orthopaedic outcomes. ⋯ Higher CFS scores are associated with poorer orthopaedic outcomes. However, it is difficult to quantify the true impact due to the limited number of high-quality studies. Further work to characterise the relationship between both gross and functional outcomes associated with the utilisation of the CFS in orthopaedic settings is essential to ascertain the utility of this simple score to improve resource allocation and provide effective consent to patients.

Currently there is no consensus on the need for investigating knee ligamentous and meniscal injuries in a patient with a tibial plateau fracture. Consequently, many soft tissue injuries are likely undiagnosed and therefore untreated. The impact this has on long term knee outcomes is not well defined. We aimed to identify the impacts of various diagnostic methods on the management of meniscal injuries associated with tibial plateau fractures and evaluate the clinical outcomes. ⋯ There is a high incidence of concomitant soft tissue injuries with tibial plateau fractures, particularly lateral meniscal injuries. There are 2 main approaches to meniscal injuries: surgeons who don't investigate, don't treat, whilst surgeons who do investigate often do surgically treat. Although studies that treated these injuries achieved good to excellent results, the currently available evidence doesn't confirm treatment superiority. As there is plausibility for better outcomes, randomised studies are needed to further investigate this clinical question.
